She is not that much into you
Enkiri/enmusubi ishi. Resembling some kind of shaggy igloo (or a sheep), this is a stone that is thought to bind good relationships tighter and sever bad relationships. You can buy a special piece of paper from the counter and write your name and wish on it. If you want to bind your love tighter, hold the paper and crawl through the tunnel in the stone from front to back. If you want out of your present relationship, crawl through from back to front. Then glue your wishing paper to the pile of others'wishes on the stone.
